Hello,

I am using PHP 5.6.24

=================My Program========================================
$link = mysqli_connect("127.0.0.1", "root", "", "testdb");

if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}

mysqli_begin_transaction($link, MYSQLI_TRANS_START_READ_ONLY);

mysqli_query($link, "SELECT name,age FROM person_table LIMIT 1");
mysqli_query($link, "SELECT name,age FROM person_table LIMIT 5");
mysqli_commit($link);

mysqli_close($link);
======================================================================

I get the following warning

PHP Warning: mysqli_begin_transaction(): This server version doesn't support 'R
EAD WRITE' and 'READ ONLY'. Minimum 5.6.5 is required in C:\xampp\htdocs\commit1
.php on line 10

And what? A clear message including the fix - what are you missing?

Hello Nobbie,

Why I am getting the warning when my PHP Version is 5.6.24. Is there any fix to this problem ? Please send me the the fix.

Regards

Deepak

Thats only MININUM requirement, did you follow http://php.net/manual/en/mysqli.begin-transaction.php? Which engine did you declare on the table?

Anyway, version 5.6.5 relates to the MySQL Version(!), whereas you are referring to the PHP Version (which is similar, unfortunately). Which MySQL Version are you running?

See above. Because the PHP Version does not matter, the MySQL Version matters.

Hello Nobbie,

I downloaded xampp-win32-5.6.24-1-VC11-installer.exe. Which version of mysql does it have ? When I open the mysql from command line

I dont know, ask Bitnami. But dont confuse PHP Version and Server Version (which relates to MySQL / MariaDB). Maybe MariaDB does not support transactions, maybe the message itself is faulty, anyway, the message tells you AT LEAST to use MySQL 5.6.5.

If Xampp / MariaDB does not support transactions, you cannot use it. Ask Bitnami.
